Title: gh-2351 Add indication that graph should be sequential

Add a new sequential flag for a graph
Occasionally (e.g., for APPLY) the actions in a graph should be
executed SEQUENTIALly, rather than in PARALLEL. This code adds
an attribute onto the graph to indicate if this is true.
applyaction.ecl is an example that requires it.

Roxie code now added.
